New Innovations in Magnetizing Stations and Magnetic Measurement from
Laboratorio Elettrofisico
By Andrea Del Prete, VP of Magnetics Technology, Laboratorio Elettrofisico

Fourth-generation magnetizing station from Laboratorio Elettrofisico

Magnetic technology solutions for every application

Every day we are facing new customer demands that are more
challenging than ever. Thanks to the experience gained in 60
years of playing a central role in this market and to the continuous research and development on innovative products, we are
able to offer the best state-of-the-art technical solutions. We are
now firmly focused on the car electrification market but always
thinking about new solutions that can be applied to all industrial
sectors.

of the company, and its R&D department is continuously working on innovative solutions. Laboratorio Elettrofisico is focused
on magnetizing as well as magnetic measuring equipment, for
which it covers one of the most complete range of magnetizing
and measuring systems available on the market. This is fundamental as customer requirements are now moving towards
100% quality control of their products magnetic properties on
their production lines.

To serve the automotive industry, currently the company is
manufacturing a fourth generation of magnetizing stations
(the first one was developed in 2016), with a handling system
and two levels of magnetic quality control. Such a magnetizing station is generally used for magnetization of step-skewed
rotors with rare earths magnets embedded. Customer's product
requirements are typically related to full magnetic saturation
and low torque ripple.

The main controls on the rotor are the total flux measurement
and magnetic scanning. For this reason, we are integrating into
our magnetizing station the possibility to check the induction at
the rotor's surface through a magnetic scan, usually performed
by a single (or multiple) gaussmeter(s) and Hall probe(s). The
acquired signal is then elaborated by a dedicated software and
displayed on an HMI panel of an industrial PC. In this way, full
magnetic quantities are available for a complete qualification of
the product: level of magnetization, skewing angle, harmonics,
etc., for each pole.

From the industrial point of view, customers asked for: low
cycle time, high performance level, compatibility with 4.0
industry, high reliability, accuracy and flexibility. Our magnetic
solutions fulfill all these requirements mentioned, as evidenced
by the fact that several OEMs and Tier 1 suppliers are using
our equipment in their production lines.

Since the necessary handling, such as rotation and axial displacement, are already provided by the bench, the addition of a
magnetic scanner is often a very convenient option. The scansion and elaboration take only few seconds, without any impact
in the production capability.

The data produced are very complete so, after giving primary
indication of the quality of a part during production, they can
also be elaborated offline by other stations, even a second
time, to provide statistic or other more in depth information.
